Xiang Xu (Sam)

PhD Student

Simon Fraser University

I am a 2nd year PhD student at SFU, advised by Yasutaka Furukawa. I am broadly interested in 3D vision and machine learning. My research focus is generation and reconstruction of structured geometry data (e.g. CAD, building). Previously, I graduated from Carnegie Mellon University with BSc in ECE, where I was advised by Kris Kitani.

SkexGen: Autoregressive Generation of CAD Construction Sequences with Disentangled Codebooks

Using disentangled codebooks to generate diverse and high-quality CAD models, enhances user control, and enables efficient exploration of the CAD design space.

Structured Outdoor Architecture Reconstruction by Exploration and Classification

A new explore-and-classify framework for structured architectural reconstruction from aerial image.

D3D-HOI: Dynamic 3D Human-Object Interactions from Videos

Monocular video dataset with ground truth annotations of 3D object pose, shape and part motion. We leverage 3D human pose for more accurate inference of the object spatial layout and dynamics.

MCMI: Multi-Cycle Image Translation with Mutual Information Constraints

Treat single-cycle image translation as modules that can be used recurrently where the process is bounded by mutual information constraints between the input and output images.

Error Correction Maximization for Deep Image Hashing

Use the Hamming bound to derive optimal criteria for learning hash codes with a deep network.
